ROBERT J. HOTOHKISS, OF DOWNSVILLE, NEW YORK.

GOVERNOR-CONNECTION.

SPECIFICATION forming part of Letters Patent No. 350,250, dated October 5, 1886.

I Application filed March 18, 1886. Serial No. 195,675. (No model.)

To all whom it may concern:

Be it known that 1, ROBERT J ULIUs HOTC'H- KISS, of Downsville, in the county of Delaware and State of New York, have invented a new and useful Improvement in Governor- Connections, of which the following is a specification, reference being had to the annexed drawings, forming a part thereof, in which Figure 1 is a side elevation of an enginegovernor to which my improvement has been applied. Fig. 2 is an inverted plan view, taken in section on line or x in Fig. 1.

Similar letters of reference indicate corresponding parts in both figures of the drawlngs. The object of my invention is to provide means for changing the speed of a steam-engine without Changing the adjustment of the governor or increasing or diminishing the steam-supply.

My invention consists in a governor having on its spindle a bevel-wheel with different series of teeth, the series being of different diameters, and in pinions carried by separate shafts and gearing with the different series, the pinions being arranged to be driven independently of each other by motion communicated to them by some rotating part of the engine. The moving parts of the governor A are supported by a hollow standard, B, in which is formed a rectangular yoke, 0, having in one side thereof a sleeve, D, arranged at right angles to the axial line of the standard. In the upper part of the standard B, above the yoke O, is journaled a hollow shaft, E, carrying a yoke, a, in which are pivoted the right-angled weighted levers b, and in the hollow shaft E is placedthe valve-rod F, which is secured in the cap 0, the cap being connected with the shorter arm of the weighted levers b by links (Z. Upon the lower end of the hollow shaft E, and within the yoke O, is secured a bevel-wheel, G, whose face in the present case is provided with two series of teeth, cf, of different diameters. In the sleeve 1), projecting from the side of the yoke O, is journaled a hollow sleeve, H, carrying on its inner end within the yoke O a pinion, g, which meshes with the teeth 0 of the wheel G. Upon the outer end of the sleeve H is secured a pulley, I, and in the sleeve H is journaled a shaft, h, carrying on its inner end a pinion, 13, which engages the teeth f of the wheel G. Upon the outer end of the shaft his secured a pulley, I,

The va1ve-rod F is connected with the enginevalve in the usual way, and a belt connected with some rotating part of the engine runs around one or the other of the pulleys I I. When a high engine-speed is required, the belt is received on the pulley I, and motion is trans- 6o niitted through the sleeve H and pinion g to the bevel-wheel G, while the pinion z, shaft h, and pulley I are driven by connection with the teethf of the wheel G. In this manner a very slow rotary motion is imparted to the 6 governor, requiring considerable velocity in the engine to effect the governor-valve. By shifting the belt from the pulley I to the pulley I motion is imparted to the governorvalve through the sleeve H, pinion i, and teeth f of the bevel-wheel G, causing the governor to revolve with a greatly-increased speed, thereby operating the governor-valve with less engine velocity.

My invention is especially applicable to en- .75

gines employed in sawing lumber, 'where a high velocity is required at one time and a comparatively low velocity at another time. This has usually been effected by the employment of a common butterfly-valve placed in the steamsupply pipe, and operated simultaneously with theshifting mechanism of the saw-mill.

- With my improvement, to secure the required change in the velocity of the engine, it

motion from the engine to one or the other of 5 the pinions, substantially as herein shown and described.

2. The combination, with the driving shaft of an engine-governor, of the bevel-wheel G,

provided with two series of teeth,'e f, the IOC sleeve H, shaft h, pinions g t, and the pulleys I I, substantially as herein shown and described.

ROBERT J. HOTGHKISS.
